Dynamic behavior of earth dams under different kinematic impacts

The paper provides a detailed analysis of the current state problem. A mathematical model is presented to determine dynamic behavior earth dams, considering viscoelastic properties soil, using hereditary Boltzmann-Volterra theory with A.R. Rzhanitsyn kernel under periodic kinematic impacts. To solve problems considered, finite element method and complex arithmetics were used reduce integrodifferential equations high-order algebraic equation. accuracy methods was verified by solving test problems. Steadystate forced vibrations Pskem dam 195 m high are studied real geometry soil resonant vibration modes. It stated that largest stress amplitudes in body occur not only first resonance, but they can other dense spectra eigenfrequencies dam, due interaction between close natural modes vibration. strength various sections tested impact Coulomb- Mohr strength; most dangerous identified terms highest stress.
